Stainless Steel Fiber Sintered Felt

High-Performance Stainless Steel Fiber Sintered Felt for Filtration and High-Temperature Applications

Stainless Steel Fiber Sintered Felt is a porous metallic filtration material manufactured by layering stainless steel fibers and sintering them under high-temperature vacuum conditions. 

Compared with conventional wire mesh filters, stainless steel fiber sintered felt offers significantly higher dirt-holding capacity, finer filtration accuracy, and longer service life.
